Mirror cut to size in Llantwit Major: what to know
Large mirrors are usually fixed with mirror adhesive and supported at the base by a slim channel or clips while the adhesive cures and afterwards. Smaller mirrors can be screw-fixed through drilled holes with decorative caps, which also lets them be removed later.
A bonded mirror follows the surface behind it, so an uneven wall can bend the reflection. We check flatness at survey, and on uneven plaster or stone walls the mirror may need a flat backing board or the wall levelling first to avoid a wavy, distorted image.
Most mirrors for internal use are made from silver-coated float glass covered by BS EN 1036-1, which sets definitions, quality requirements and test methods, including resistance to damp and corrosion. Mirror for bathrooms or other humid areas should come from a supplier whose product meets that standard.
To protect the edges, spray glass cleaner onto a soft cloth rather than directly onto the mirror, so liquid does not run down and soak into the bottom edge. Avoid harsh or abrasive cleaners, and dry the edges after cleaning in bathrooms.

About Llantwit Major for this job

- Coast
- Llantwit Major is about 1 km from the coast or a tidal estuary, so salt air and wind-driven rain are worth planning for. Mirrors are fitted indoors, but salty, humid coastal air can still reach the silver backing through exposed edges, particularly in bathrooms and near entrances. Protected edges, a compatible adhesive and good ventilation all help prevent black edge corrosion.
- Daylight and sun
- In Llantwit Major the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. A mirror opposite or beside a window reflects daylight deeper into a room, which helps dark north-facing spaces through winter. Low direct sun on a large mirror can cause glare, so its position and any tint are worth considering.
- Access and setting
- Older rural homes often have uneven walls of stone or lime plaster, which can distort a bonded mirror unless the wall is levelled or a backing board is used. Damp solid walls also need checking before a mirror is fixed to them.
- Rules in Wales
- In Wales, Approved Document N covers safety glazing: safety glass is needed in and around doors and in low-level glazing where people could walk into it.

Bespoke Mirrors in Llantwit Major: questions
How should I clean a mirror without damaging it?
Spray glass cleaner onto a soft, lint-free cloth rather than directly onto the mirror, then wipe and buff dry. That stops liquid running down and soaking into the bottom edge, which is where black edges usually start. Avoid abrasive pads and harsh chemical cleaners, and dry the edges after cleaning in bathrooms.
Why do mirrors go black around the edges?
Black edges are corrosion of the silver layer behind the glass, usually caused by moisture or cleaning fluid getting into the edges, or by an adhesive that reacts with the backing. Bathrooms are especially at risk because of steam. The damage cannot be reversed, so the mirror needs replacing, ideally with better edge protection and a compatible adhesive.
What edge finishes can I choose for a bespoke mirror?
The main choices are a flat polished edge, a bevelled edge and an arrised edge. Polished edges give a clean, frameless look and suit mirror walls, bevels add an angled border that catches the light, and arrised edges simply take off the sharpness where a frame or channel will hide them. Bevel width can usually be chosen too.
Can I have a bespoke mirror in a bathroom?
Yes, provided the room is well ventilated and the mirror is protected from standing water. We use mirror that meets the relevant standard for internal use, bond it with a compatible adhesive and keep edges away from splashes where possible. A heated demister pad can keep part of the mirror clear, wired in by a qualified electrician.
